I am new to wire feed welding...have always used a stick welder for hobbyist projects.
I bought a Hobart 500549 Auto Arc 130 Wire Feed MIG Welder. I am using flux-cored wire. When I weld sometimes the wire will not flow smoothly, but will pulsate...if I press the trigger on the gun while I am not welding it doesn't do this.
The other challenge I have is that it will occasionally stop feeding the wire all together. I will stop welding for an hour and then it will work again. ??
I have tried different tensions, and wire feed settings. I have replaced the tip a few times. I am holding the tip about 1/2" from the puddle.
